I picked this up at a local auction recently and posted a few pictures of it and my Irwin-Pedersen on another thread on this forum. I like that both guns came from the same factory and are only about 22,000 serial numbers apart. I was able to borrow a better camera and took these pictures.

This mark is on the left side of the receiver below the wood line. Not sure what it means.

This is the right rear of the receiver, behind the operating slide slot. I'm not sure if this is a sideways 'D' or part of a flaming bomb ordnance mark.

Recoil plate and marking on the bottom of the recoil plate.

Cartouches on the right side of the stock.

Sling well.

Upper handguard inside edge.

Stock heel.

High wood with 2-rivet handguard. There is a mark on the operating slide arm just visible here.

Here is a better view of the mark on the operating slide arm. Possibly a sideways 'flaming bomb'?

Barrel maker marking and proof mark.

Front sight left side. Right side is unmarked. Top has an 'N' mark behind the blade.

Rear sight left and right sides.

Butt plate rim.

Bolt and right lug.

Extractor and plunger.

Firing pin.

Trigger housing left and right rear with marking.

3 views of the hammer.

Hammer spring - 22 coils.

Mag catch. Hard to see but there is an 'I' (without serifs) to the left of the 'P'.

Narrow, flat (not grooved) mag well rear wall.

This upside down 'B' is on the left side of the operating slide box. I'm not sure what it means.

Safety.

Sear and sear spring with tapered ends.

Trigger with IP/S'G' notch and trigger spring.

I haven't shot it yet, and am open to suggestions from the forum as to whether I should or not. My Irwin-Pedersen is more of a mixmaster, so I'm more inclined to shoot that one and keep this one for show. Thanks in advance for your input/thoughts.

I have a mark very similar to the one on your operating slide handle inside my SG hand guard. I have considered it may be a flaming bomb, but it looks like a tool mark. There would have been no reason for a tool mark on your slide. Looks like an Underwood recoil plate sneaked in there, but if it looks like the rest of the gun, it probably belongs there. My SG has one component that could be called suspect, a type one unmarked sear. Documentation calls for a type 2, but the part looks just like all the other parts and I believe it to be original.

I would for sure test fire the gun to make sure it functions, but I would not use it as a shooter. You have a fine piece there.

Looks pretty honest and very similar to the one I have about 20,000 later with I think an 8-43 Underwood barrel. Wonder if that receiver mark is a remnant of the stamps in the same area on some earlier IP Carbines? Could that mark be part of a flaming bomb? ETA, yes, that's a flaming bomb stamp. Mine has it but deeper.

Also, I don't think I've ever found a Carbine that didn't have 1 anomaly contained in it, from engraved initials (like LEVI or SS# on the trigger housing and FIRE scratched on the safety of an early Win), sanded off cartouches, shaved ears and even a type I band turned into a bayonet band. The Prime I have like yours it looks like someone changed the hammer, which I suspect could've been an IP hammer or it was accidentally changed during a tear down party. Believe it has an IP rear sight base with a Prime marked leaf.

ETA, like yours mine has the visible circle around the P stamp on the barrel, which is 8-43 dated. The slide has the same bomb stamp location too. Slide and receiver stamps are both J. Safety is IP-A, catch is B-IP, sear is S'G', front sight is only N marked and the oddball barrel band is marked UI. Recoil is S'G' type III. Rear sight base is B-IP, leaf is B-S'G'.

Here is a better view of the mark on the operating slide arm. Possibly a sideways 'flaming bomb'?

Yes, a flaming bomb. My S'G' is only 2000 later than yours, with an Underwood 8-43 barrel and has the same, though lighter, stamping. I also have a "B" on the left side and "S'G'" in the bottom well of the slide (though the latter is very hard to see with the swirl marks from the endmill cleanup machining).

One sold on GBroker about 3 months ago for $729 buy it now from a West Coast pawn shop. During that time I saw about 3 others from the West Coast from different sellers/auctions in original condition sold for low money. I got one but was unable to get the others.
